I love woothemes, have used them on many sites and can’t say enough about their quality and even more importantly their level of professionalism and timely support. They have a fantastic offer going on right now until the end of the year that you can use to get 5 themes for the price of one OR 20 percent of any of their subscriptions.
With the number of themes they currently have and the amount they release on a consistent basis I personally am a huge fan of their developers package which is an awesome deal now as well. Take your pick, just remember to pick them up before the year is over because like all good things, this too will be coming to an end.
